Abstract
For purpose know sterilization competence in killing bacteria and parasites and extent fitting it's for environmental measurement, samples of water were taken from three stations of river of Euphrates and for many times (the first station was represented the stage before sterilization as for second station was sterilization or treatment stage , third station was after sterilization ), during the period from winter until autumn 2013. The samples transferred to the laboratory and examined by MPN method for examine number of bacteria E. coli in water and rate it's in autumn was (1736.6) cell/ 100 ml , in spring were (1139) cell/ 100 ml, summer (1136.6) cell/ 100 ml, while winter (1038) cell/ 100 ml. As for sedimentation, the highest rate of bacteria was in autumn (2066.6) cell/ 100 ml followed by spring (1933.3) cell/ 100 ml then summer (1550) cell/ 100 ml finally winter (1340) cell/ 100 ml . And sedimentation method for parasites and 13 types of parasites were isolated from water of these three stations while only seven of these type of parasite were found in sedimentation of those stations.
Water and sedimentation of first station was contaminated with parasites with rate (26.3%), (62.5%) and water and sedimentation of second station (36.8%), (25%) and water and sedimentation of third station (36.8%), (12.5%) respectively. Parasite Giardia lamblia was the most exist in water with rate (26.3%). As for Ascaris lumbricoides was the most exist in sedimentation with rate (25%).Results of study showed clear conformity between temperature of air and temperature of water in all stations of study ,and range of temperature of air was between (14.2- 41.2) and temperature of water was between (10- 33.5) . Values of pH were bent to weak alkaline with range (7.50 -8.76). Electrical Conductivity recorded values between (2375 – 5843) μS/cm as for salinity was (1.52 – 3.74) ppt , water of river was represented a few salinity , as to values dissolved oxygen werebetween(5.67-11.5)mg/L.
